v Lvn-srnmor LIFTER.

To all whom it may concern."

Be it known that I, EARL E; Trmz'nrs, a citizen of the United States, residing at Hebron, in the county of Thayer and State of Nebraska, have invented certain new and useful Improvements in Valve-Spring Lifters; and I do hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in valve spring lifters especially adapted for use on internal combustion engines of the type employed in Ford automobiles and has for one of its objects the provision of a device of the above stated character wherein the spring of a puppet Valve used in the above named engine can be lifted and supported in a raised position by said device so that both hands of the operator or mechanic can be used to remove the locking pin of the valve.

Another object of this invention is the provision of a valve spring lifter of the above stated character which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention reference is to be had to the following description and accompanying drawing in which,

Figure 1 is a fragmentary sectional viewv of an engine illustrating a valve spring lifter applied thereto and constructed in accordance with my invention,

Fig. 2 is a side elevation of the valve spring lifter,

Fig. 3 is a fragmentary plan view of one of the arms of the lifter.

Referring in detail to the drawing, the numeral 1 indicates an engine having the usual puppet valves 2 held in closed position by valve springs 3. The engine 1 is provided with the usual removable head 4 which can be removed to clean the engine and expose the valves and valve seats. The valves are held closed by springs which specific tion of Letters Patent. P t t d J y g 192 1919. Seria1No.312,491.

seat against pins 16in the valve'stems. In order to remove one of the valves 2 from the engine it is necessary that the pin 6v be removed in order to do this, the spring has to be compressed or raised upwardlyand' this is accomplished with my tool; I 1

A horizontal arm 7 isadapted' to'be associated with the engine 1 and one end thereof engages or rests on the head of the valve to be removed, while the other end of the arm 7 has formed thereon an upwardly and outwardly extending handle 8 to which is connected a ring 9. The handle 8 as will be noted by the drawing is disposed a short distance from the side of the engine. A handle 10 is pivoted to the arm 7 at a point adjacent the formation of the handle 8 to said arm and the arm 10 extends above and below the arm 7 and has formed upon its lower end a horizontally disposed arm 11 which extends parallel with the arm 7 and in a plane below the same. The free end of the arm 11 is enlarged as illustrated at 12 and bifurcated to form a slot 13 that opens outwardly through the edge of said enlarged portion so as to receive the lower end of the valve stem. The top face of the enlarged portion 12 is concaved as illustrated at l t to form a seat adapted to receive the washer 15 on the valve stem and which is interposed between the key or pin and the lower end of the valve spring so that on moving the handle 10 in the direction of the handle 8 the spring will be compressed and also the washer 15 raised upwardly on the valve stem, freeing or relieving the pressure on the pin or key so that the same can be readily removed from the valve stem. When the spring has been compressed and the washer raised the handle 10 is in close proximity to the handle 8' and the ring 9 is swung over the handle 10 to lock the handles against movement in relation to each other.

Owing to the fact that the arm 7 engages the valve head, said valve is held against upward movement. After the spring has. been compressed and the handles locked together the tool may then be released and will support itself in such a position with the spring compressed so that the mechanic is free to use both of his hands for other purposes such as removing the pin or key from the valve stem.

Vhile I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope'of. the invention" as claimed.

Having thus described my invention,-vvhat .I claim 1s:-- ,A valvev spring lifterc'omprisinga horiv zontally disposed arm adapted to rest on the head of a valve, an" outwardly and up- 1 wardly inclined handleformed-on said arm,

end of the second handle and extending at right angles to the second handle and in a plane below the first arm, an enlarged portion formed on the end of the second arm and having a slot opening outwardly through "one edge thereof and having a eona caved recess in its upper face, and a ring pivoted to the first handle and-adaptedto enga e over the second handle When said hand es are moved in parallelism.

In testimony whereofI aflix my signaturein presence of two witnesses.
